Description
- This application claims priority benefit of Korean Patent Application No. 10-2005-66531 field on Jul. 22, 2005 and Korean Patent Application No. 10-2005-81671 field on Sep. 2, 2005 to Byung-Shik Kim, which is hereby in corporated herein by reference.
- The present invention relates to a deep drawing core for a sandwich panel being manufactured by a deep drawing process and a sandwich panel for decorating a structure using it, more particularly to a deep drawing core obtained by forming a great number of a sort of hollow part selected from conical, elliptic conical, or pyramidal hollow parts in any one surface of the upper or lower directions of a metal plate, or in both surfaces thereof by a deep drawing process using a drawing die and a sandwich panel for decorating a structure manufactured in accordance with the conventional process for preparing a sandwich panel by using said obtained deep drawing core.
- Up to now, a sandwich panel for decorating a structure has been manufactured by layering
adhesive layers honeycomb core 5 as shown inFIG. 7 or acorrugation core 5 as shown inFIG. 8 , by layering metal ornonmetal plates - However in case that a sandwich panel is manufactured by a plastic sheet core, because the plastic sheet core is melted or burned easily by heat, in result, poisonous gases are generated, and thus they are not suitable as an incombustible construction material needed actually.
- In case that the a sandwich panel is manufactured by using said honeycomb core or
corrugation cores 5, when a certain part of the panel is cut in V type groove vertically or horizontally and then the grooved part is bent in order to carry out on bent part of a structure, due to structural defect of a core forming the sandwich panel the panel is not cut or bent precisely. - For examples, in case that the
honeycomb core 5 is inserted in the sandwich panel, as shown inFIG. 7 , because the upper and lower metal ornonmetal plates core 5 are adhered bylinear adherend 12 having weak adhesion, when the panel is cut in V type groove and the grooved part is bent thelinear adherend 12 is damaged or separated easily. Accordingly function of the sandwich panel lowers. Also the sandwich panel having thehoneycomb core 5 has fault that the cutting process is more difficult than that of flat plates owing to continuous honeycomb structure. - In case that the
corrugation core 5 is inserted in the sandwich panel, as shown inFIG. 8 , because bending portion of thecore 5 and the upper andlower plates linear adherend 12 is separated easily and thereby the function of the panel is damaged and lowers. - Also because the
core 5 corrugates, when theV type groove 8′ is formed in the sandwich panel having thecorrugation core 5, since it corresponds tobent groove 10 of thecorrugation core 5 supporting function of the upper andlower plate core 5 lowers remarkably. - Accordingly its bent outer surface also is not smart or smooth.
- Furthermore when the bending portion corresponds to
hill 12 of the corrugation since the whole of thecorrugated portion 11 are cut the bending portion and its outer surface are not smooth. - Therefore, the sandwich panel inserted the
corrugation core 5 is not cut and not bent freely vertically or horizontally but thegroove 8 is formed entirely only in vertical direction to the corrugation to give smooth outer surface by bending. - The present invention is to solve the problems of conventional sandwich panels using honeycomb or corrugation cores.
- Particularly, the object of present invention is to provide a core for a sandwich panel and a sandwich panel using the core that on the sandwich panel a V type groove can be cut and bent easily when the bent sandwich panel is made to carry out on bent portion of a structure.
- More particularly, the present invention is characterized that any one kind of metal plate selected from metal plates such as an aluminum plate, a tin coating plate, a zinc coating plate, a stainless steel plate is pressed by means of a deep drawing process using a drawing die to form a great number of any one kind of hollow part selected from conical, elliptic conical, or pyramidal hollow parts such as trigonal tetragonal or octagonal pyramidal hollow parts having a flat bottom on the metal plate, wherein said hollow parts are sunk only in any one direction of the upper or lower directions of the metal plate, e.g. downwardly, or alternately downwardly and upwardly therefrom, to give a core for a sandwich panel, and using the resulting core a sandwich panel is manufactured by conventional process for preparation thereof.
